Well, with version 18.104.22.16888 of the desktop product, PlayOn has become all but useless to me. DirecTV Now was removed from the channel list, and that takes the cake. I have watched over the last year as channel after channel has disappeared without explanation, Comedy Central, USA, Syfy, CNN, A&E, TNT, TBS, FX, History, Discovery, Disney, and Bravo. Even all the freely available news channels like Fox News, CBS News, NBC News, and Newsy, and the free sports channels like NBC Sports & Fox Sports are gone. The streams from these channels can be captured legally with freely available open source tools. PlayOn provided the automation glue that combined all this into one place.
And sadly the utility of this tools has ended. My gut told me that the usefulness of this tool wouldn't last, and I guess my gut was right. So long PlayOn, and thanks for 3 years of good use.
